Will railguns quickly replace conventional naval guns, and why are uncrewed surface vessels difficult to develop?
Short answerNo, conventional guns will persist while costly early railguns mature, and uncrewed ships face a hostile marine environment that makes reliable navigation and survival unusually demanding.
NotesConventional guns are expected to remain important even if railguns eventually become practical. Early electromagnetic weapons will be expensive while navies learn how to build, power, and sustain them. The comparison with uncrewed surface vessels shows how first generations must cope with a marine environment that continually pushes craft off course and toward hazards. Unlike aircraft, a ship can be driven into rocks while still afloat, making reliable navigation a central design problem.
